Keyboard/Mouse
The PCM-53E52 is equipped with a keyboard and mouse interface. Both the keyboard and the mouse
utilize the same PS/2 connector (JK1) through the use of the included Y cable. Though a standard PS/2
keyboard can be plugged directly into the connector, to be able to use both a keyboard and mouse you
must use the Y adapter cable or a serial mouse.

hard drive. The DOC is a paged memory device and is mapped at segment address D000 Hex, and by
use of the device’s firmware emulates a hard drive. Thus most operating systems will be able use the
device similar to a hard drive.

it in backwards, and turning on power, can
destroy
the DOC and
damage
the
PCM-53E52 rendering both inoperable! Any information on the DOC will be
unrecoverable at this point.

the board and reinserted, prior to turning the power back on.
